Cap for flashing



Patented July 26, 1932 yerissi'. Orres CHARLES A. EARLEY, OF DORCI-IESTER, MASSACHUSETTS CAP FOR FLASHING Application led December 26, 1931. Serial No. 583,219.

This invention relates to improvements in sheet metal flashing, and particularly to a cap therefor.

rlhe object of the invention is to provide a cap for a strip of flashing, the latter being of a type such as is inserted in the binding material of a wall between courses of masonry and utilized to forni a waterproof cut-off course and the cap being utilized to form a drain above the flashing through the binding material to the exterior of the wall.

The invention consists in a cap for fiashing as set forth in the following specicat-ion and particularly as pointed out in the claims thereof.

Referring to the drawing Fig. 1 represents a plan view of a cap for flashing embodying my invention.

Fig. 2 is a vertical section through the wall of a building illustrating my improved cap, together with the flashing with which it is associated inserted between courses of masonry at several locations upon said wall.

llig. 3 is an enlarged sectional view through a portion of a wall taken transversely of the cap at a location intermediate the transverse arches and at a position upon the wall as indicated by the lines 3 3 of Fig. :2.

llig. 4 is a. view similar to Fig. 3 but is taken transversely of the cap in a plane in which the transverse arches thereof are located.

Fig. 5 is a sectional View through a portion of the Wall upon the longitudinal median line of the cap.

Like numerals refer to like parts throughout the several views of the drawing.

ln the drawing, 6 represents a cap, preferably constructed of pressed sheet metal and embodying therein oppositely disposed flat marginal portions 7 which extend longitudinally of the cap in the same plane, and an arch portion 8 which is interposed between the marginal portions 7 and also eX- tends longitudinally of the cap. At` one end of the cap the arch portion is curved downwardly at 9.

Also embodied in the cap 6 are a plurality of other arch portions 10 which extend transverscly across the marginal portions 7 upon opposite sides of the arch 8 and intersect said lastnamed arch. When the cap 6 is placed upon a strip of flashing a passage 11, constituting a drain, is formed between the arch 8 and the flashing, and other passages 12 are 55 also formed between the arches 10 and the flashing, and these last-named passages all communicate with the passage 11.

In Fig. 2 I have illustrated a conventional form of wall in which strips of flashing of any suitable form having caps 6 embodying my invention resting thereon are positioned at locations indicated at A, B and C. The wall embodies therein avcoping 18v and a plurality Iof courses of brick 14, all of which are joined together in a well-known manner by a suitable binding material 15. A strip of flashing 16 is inserted at A in the binding material 15` between the coping 13 and the uppermost layer of brick 14, and caps 6 em- 70 bodying my invention are placed at regular intervals along the strip of flashing 16 and extend transverselyv thereacross.

During the construction of the wall, after the caps 6 have been placed in position upon the strip of flashing, both flashing and cap are covered with a layer of the binding material, and it is evident that the cap 6 will act to hold the binding material that is located thereabove spaced apart from the flashing, and a passage constituting a drain will be provided beneath the arch 8, which will extend entirely across the wall, and at the location A the passage 11 may drain both at the front rear faces of the wall. The flashing itself forms a waterproof cut-ofi' course between the course of masonry located thereabove and therebelow and Water which may collect upon said flashing will be conducted to the exterior of the wall by means of the several drains. Y Atthe location B upon the wall, a strip of flashing 17 provided with a downwardly turned flange 18 is located, but as this flashing is located above a roof 21, the caps 6 of this invent-ion may be placed in exactly the same manner as previously described in connectionv with the dashing 16, and the passageway 11 beneath the arch 8 may drain at either the front or rear faces of the wall.

At the location C, which is at a position upon the wall above a window and below the roof 21, a strip of flashing 19 has an upwardly bent flange 20 embodied therein and as m-oisture often collects above the flashing between the inner face of the flange 20 and the adjacent face of the wall, it is desirable that said moisture shall be discharged at the front of the wall. In this case the caps 6 of my invention rest upon the flashing 19 eX- tending transversely thereof, and the rear end of the cap abuts against the upturned flange 20 and communicates with any space that there may be between said flange and the wall in such a manner that moisture collecting in said space will flow through the passage 11 and be discharged at the front of the wall. The transverse passages 12 are provided for the purpose of enabling the moisture which may collect upon the strips of flashing to communicate with the main passage 11 beneath the caps. The curved end portion 9 of the cap preferably projects a slight distance outwardly beyond the face of the wall and acts to prevent water which may run down the wall, or be driven thereagainst by the wind,`from entering the outlet of the drain.

I claim:

1. A cap of the character described comprising a strip of sheet material having an arch portion lembodied therein and extending longitudinally thereof, and a plurality of other arch portions extending transversely of said strip and intersecting said longitudinal arch. I

2. A cap of the character described comprising a strip of sheet material having flat marginal portions embodied therein and eX- tending longitudinally thereof, an arch portion also extending longitudinally of said strip between said marginal portions, and a plurality of other arch portions extending transversely across said marginal portions and intersecting said longitudinal arch.

3. In a masonry wall the combination with a strip of flashing and layer of binding material thereon of a cap resting upon said flashing and extending thereacross, said cap having an arch portion embodied therein eX- tending transversely of said wall and holding the binding material thereabove spaced apart from the flashing, whereby a drain is formed beneath the arch communicating with the eX- terior of the wall.

4. In a masonry wall the combination with a strip of flashing and layer of binding material thereon of a cap resting upon said Hashing and extending thereacross, said cap having flat marginal portions and an intermediate arch portion embodied therein extending transversely of said wall and holding the binding material thereabove spaced apart :from the fiashing, whereby a drain is formed my hand.
